Benefits of technology
The patent aims to provide a method, device, and system for wireless communication that can improve the efficiency of uplink power control and reduce the burden for uplink control channel transmission of a macro cell. This is achieved by transmitting all first uplink signals of the uplink signals to a low power node as a receiving node.
Problems solved by technology
In addition, when the macro base station and the low power node perform CoMP (Coordinated Multi-Point) transmission, and particularly for a case where the macro base station serves as an uplink receiving node, it is unable to perform accurate power control.
Further, a solution that takes the macro base station as a receiving node to perform uplink power control is not beneficial to reduce energy consumption of UE (User Equipment).

A method, device and system for performing wireless communication in a wireless communication system. The wireless communication system includes a low power node and a macro base station with common baseband and user equipment, and the user equipment communicates with the low power node and the macro base station via a plurality of component carriers. The method includes: receiving, by the user equipment, a downlink signal transmitted by the low power node and the macro base station; and transmitting uplink signals to the low power node and the macro base station, wherein the method further includes: transmitting all first uplink signals of the uplink signals to the low power node as a receiving node. According to the method, device and system, it is possible to improve the efficiency of uplink power control of a terminal and / or reduce the burden for uplink control channel transmission of a macro cell.
Description
FIELD OF THE INVENTION[0001]The disclosure relates to the technical field of wireless communication, and particularly to a method for performing wireless communication in a wireless communication system, a wireless communication device and a wireless communication system.BACKGROUND OF THE INVENTION[0002]This section provides background information related to the disclosure, which is not necessarily prior art.[0003]Carrier aggregation before LTE (Long Term Evolution) Rel-11 is carrier aggregation of a single base station node. An aggregated carrier of a terminal is constituted of one primary component carrier and at least one secondary component carrier. In a FDD (Frequency Division Duplex) mode, association between a downlink primary component carrier and an uplink primary component carrier is determined via a SIB2 (System Information Block 2) message. A PUCCH (Physical Uplink Control Channel) signal is transmitted on the uplink primary component carrier. Normally, only one uplink c...
